Inline Code Generation
With the Inline Code Generator, you can generate code by writing a prompt in natural language. For example, typing “Generate a Python function to calculate the factorial of a number” will prompt Cursor AI to create the entire function for you. This feature saves time and reduces the effort needed to structure new code.
Copilot : Advanced Code Prediction
Cursor AI’s Copilot feature is an advanced version of GitHub Copilot, predicting entire blocks of code rather than just single lines. This helps in writing and refining code, especially in complex projects like React components, by suggesting multi-line code structures.
Error Correction and Debugging
Cursor AI continuously checks your code for errors and provides instant suggestions to correct them. This real-time error detection and correction help prevent potential bugs and save time in the debugging process.
Code Base Questions
This feature allows you to ask questions about your codebase, such as locating specific functions within your project. You can query Cursor AI to find functions or clarify complex concepts, eliminating the need to manually search through hundreds of files.
Natural Language Prompts
Cursor AI supports natural language prompts, allowing you to write code by describing what you need in plain English. For instance, typing “Create a function that checks if a number is prime” will generate the corresponding Python code. This feature is particularly useful for beginners or when working with unfamiliar languages or frameworks.
Integration with VS Code Extensions
Cursor AI is built on VS Code and is compatible with many VS Code extensions. It works seamlessly with Git and other version control systems, and it maintains full AI functionality even when connected to remote servers via SSH. This integration enhances your coding environment with additional tools like linters and debugging tools.
Real-time Collaboration

Cursor AI - Performance and Accuracy
Evaluating the Performance and Accuracy of Cursor AI
Performance
Cursor AI’s performance is enhanced through several technological and architectural choices:- Mixture of Experts (MoE) Architecture: This architecture integrates multiple expert models to handle different tasks, which can enhance overall performance and accuracy.
- Engineering Performance Optimization Techniques: Techniques such as KV caching, local caching, speculative decoding, and prefix-cache are likely employed to boost the model’s speed without compromising accuracy.
- Collaboration with Local Small Models: This approach reduces reliance on cloud resources, thereby speeding up response times, allowing for faster and more efficient code completion.
Accuracy
The accuracy of Cursor AI is improved through several mechanisms:- Contextual Understanding: Cursor AI can generate more accurate and relevant responses by using the context of a defined reference, incorporating files, folders, and documents to enhance the precision of the output.
- Next Action Prediction: Features like Copilot predict the next edit or action a developer might take, providing accurate and timely suggestions based on previous actions.
- Continuous Improvement: The model benefits from continued pre-training and post-training on large parameter code models, refining its predictions and accuracy.
Limitations and Areas for Improvement
Despite its advancements, there are some limitations and areas where Cursor AI can improve:- Repetitive Errors: Users have reported that the AI sometimes fails to learn from authoritative sources or previous interactions, leading to repetitive errors, which is particularly frustrating in a coding context.
- Lack of Long-Term Memory: The AI does not have a long-term memory to recall previous interactions or learn from them effectively, resulting in users having to correct the same mistakes multiple times.
- Version Control and Auto-Save: While the auto-save feature is convenient, it can be problematic if users need to revert to a manually saved version. Improving version control and making manually saved files easily accessible could enhance user experience.

The AI learns the developer’s coding style and adapts its suggestions accordingly. This personalized approach ensures that the help provided feels more aligned with the developer’s preferences and project rules.Enhanced IDE Experience
Cursor AI has its own IDE, which is similar to Visual Studio Code. This setup provides a smooth and integrated experience, making features like code completion, code generation, and debugging work seamlessly together. This can significantly boost productivity and reduce distractions.Multi-File Code Generation
Cursor AI can generate code across multiple files, which is particularly useful for complex projects. The diff-viewer UX helps in quickly showing the changes applied to the codebase, making it easier to manage and review code.Natural Language Instructions
Developers can write code using natural language instructions, updating entire classes or functions with simple prompts. This feature makes coding more efficient and accessible, especially for those without extensive coding experience.Disadvantages of Cursor AI
Despite its advantages, Cursor AI also has some notable disadvantages:Limited IDE Integration
Cursor AI works best within its own IDE and does not integrate easily with other popular IDEs. This can be a problem for developers who prefer using different IDEs, as they may face compatibility issues and a less smooth experience.Potential Learning Curve
Switching to Cursor AI’s IDE, even though it resembles Visual Studio Code, can be challenging for developers accustomed to other IDEs. There may be a need for time to adjust to the new workflow and learn how to use its features effectively.Reliance on Cursor AI’s IDE
The reliance on Cursor AI’s own IDE can be a drawback for developers who have specific project needs or prefer other IDEs. This dependency might limit flexibility in certain development environments.Bugs and Crashes
Some users, particularly those on Ubuntu, have reported experiencing bugs and crashes. This instability can affect the overall confidence in the product’s stability and support compared to more established IDEs like VS Code.Instruction Inconsistency
There have been reports of the AI ignoring user-defined instructions more frequently in newer versions, and some prompts may require multiple iterations to achieve the desired outcome. This inconsistency can hinder the efficiency of the tool. By considering these points, developers can make a more informed decision about whether Cursor AI aligns with their needs and preferences. Cursor AI - Comparison with Competitors
